After research shows them that they've failed in their mission of blending in as a normal, average American family, the Solomons strive to correct the problem by moving into a bland, beige apartment, dressing less oddly, and eschewing all that has made them stand out. Sally joins the tenants' association and becomes obsessed with making everyone in the complex adhere to the strict guidelines imposed by the group. When Dick meets a visiting professor whom Mary finds charming because of his eccentricity, Dick realizes he has erred in abandoning his individuality. He, Tommy, and Harry conspire to get Sally to hoist herself on the petard of her own narrow-mindedness, getting them all evicted so they can return to their beloved attic apartment.
